windows 7 for 40$ - what about this ?

"This is not the retail version from the store shelf, but it is the one that Microsoft gives out at IT Professional Conference Meetings to Engineers and Sales Professionals who are invited to come to these meetings.

Since it does not have the "Activation" policy files attached to the disk,it was not sold to the public,instead it is used to promote their software which is a regular practice with Microsoft Corp.

It is not a beta version, trial version, pre-release or anything like that.

Although this is a copied DVD and not an "official Microsoft disk" it works exactly the same,and has even more benefits since it has no activation files, it can be installed unlimited times on as many computers as you like which is a big plus! "
